To aZZ whom it rmty concern:

Beit known that 1, JAMES C. SHERB RNE, a citizen of the United States,residing at Des Moines, in the county of'Polk and State of Iowa, haveinvented certain new and useful Improvements in Machines for ProducingHot-"Air Currents and Liquid Spray, of which the following is aspecification. The objects of my invention'are to provide a machine ofsimple, durable, and inexpensive construction adapted for the relief ofheadaches, neuralgia, rheumatism, and simi lar ailments.

More specifically, it is my object to provide a machine that will beeasily operated by footpower and that will when operated produce an evenregular current of air heated to any desired degree and dischargedthrough a hose or pipe to be applied to the person of the patient at.the point where it is desired torel-ieve the pain and cure the disease.

A further object is to provide means whereby a liquid spray maybeautomaticallyinjected into the hose or pipe, so that curative remediesin liquid form may be commingled with the hot air to aid intheic-u'rat-ive properties of the air-current, and,'further, to providean improved nozzle for the pipe or hose,'whereby the air-current andliquid spray may be applied to the person of the patient in such manneras to heat and spray'a greater or less surface of the body and wherebythe temperature to which the parts of the bodyare subjected may beregulated with the greatest accuracy.

Myinvention consists in certain details in the construction,arrangemenaand combi-.

nation of the various parts of the device wherebythe objectscontemplated are attained, as hereinafter more fullysetgforth,'

pointed out in myclaims, andillustrated in the accompanying drawings, inwhich- Figure 1 shows a perspective View of the complete apparatus readyfor use. shows a vertical central sectional view of same with'the hoseand liquid-spraying device omitted. Fig. 3 shows "an enlarged detailsectional view of my improved nozzle, and Fig. 4 shows an enlargeddetail view of the valve interposed between the pump and the equalizingpressure-bag.

Referring to the accompanying drawings, I

Fig. 2'

have used the reference-numeral to indicate the machine-frame. Thisframe is provided with two horizontal shelves or parti- 'tions 11 and12, and at one side of the frame is a hinged door 13 to provide accessto the space beneath the partition 11. a A second hinged door, 14,provides access to the space between the partitions 11 and 12,aud ahinged door 15 provides access to .thespace above the partition 12.Mounted on the interior, of the machine-frame beneath the partition 11is an air-pump 16 of ordinary construction.

A treadle 17 is attached to its piston rod and projects outwardlythrough a slot 18 in the'do'or 13, and an extensile coil-spring 19 onthe piston-rod of the pump serves to normally elevate the foot treadle.Communicating with the pump 16 is a flexible tube 20, which passesupwardly through the central portion of the partition 11. At the upperend of the tube 20 is a'one-way valve 21 of ordinary construction, fullyillustrated in detail in Fig. 4.

This tube 20'communicates with an expanding rubber bag 22, which bag isinclosed in a wire-netting 23, which limits the expansion of therubber-bag. A tube or pipe 24 communicates-with the upper end of therubber bag and "also with a metal coil 25. This coil is contained withina water-tank 26, which tank is provided with a funnel 27 at its upg perend and is detachably secured to the brackets 28 on the interior of themachineframe. The'bott-om of the tank preferably projects a slightdistance beyond the sides of Y the tankproper and is perforated at 29. A'thermometer30 is secured to the tank and may be seen from the exteriorof the machine through a glass 31 -.-over an opening in themachine-frame; Beneath the tank I place one or more lamps 32, bywhichthe water in the-tank is heated. Leading from the coil 27 is adischarge-pipe 33, which projects through the machine-frame, and a valve34 provides means whereby the flow of air through the pipe 33 may beregulated to any desired degree or entirely stopped. On'the exterior ofthe machine-frame is a shelf 35, designed to support a vessel 36,containing a liquid healing preparation. A tube or pipe 37 communicateswith the pipe 33 and discharges into the vessel 36, and a second similartube, 38, communicates between the vessel 36 and the pipe 33, and valves39 are provided in said tubes whereby the passage -ways through them maybe adjusted as to size or shut-off.

' The numeral 40 indicatesa hose ortube having a nozzle 41 at its end.In Fig. 3 I have shown amodified form of this nozzle, in which thenumeral 42 indicates a bell-shaped head on the body portion 43, which isto be connected with the hose 4:0, and within the bellshaped head is adeflector 44E, so arranged as to close the bell-shaped opening except atthe outer edge thereof. This deflector is connected with a cross-piece45 on the interior of the bell-shaped end.

In practical use and assuming that it is desired to apply a current ofhot air and liquid spray, the operator may seat himself near themachine-frame and by placing one footupon the treadle may operate thepump to force air into the expanding rubber bag. WVhen the bag has beenfilled, the air cannot pass downwardly through the pipe that supplies iton account of the one-way valve therein, and hence the rubber bag willforce air upwardly at a uniform pressure because the tube leading fromthe rubber bag is of less capacity than that leading to the bag.Obviously the water tank in which the coil is contained may be i'irstheated to the desired degree by the lamps, and when it is thus heatedthe operator may by observing the thermometer determine when the desiredtemperature is reached. The pipe leading from the coil communicates withthe hose, and the valve therein provides means whereby the flow of theair may be regulated. If it is desired to commingle withthe air a sprayof liquid, the operator then connects the tubes 37 and 38 with the pipe33, containing the liquid, and when the valves 39 are opened a portionof the current of air in the hose 40 will flow into the bottlecontaining the liquid and will carry away from said bottle a spray ofthe liquid through the tubes 38 into the hose 40, and by means of thebell-shaped nozzle a current of air and spray may be applied to thebody. A small space only would be reached if the nozzle were placedclose to the body, or a less temperature may be obtained over a largerarea of the body by simply removing the nozzle a slight distance fromthe body.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States therefor, is-

1. In -a device of the class described, the combination of amachine-frame, an air-pump therein, an expanding bag communicating withthe air-pump, a water-tank, means for heating the water, a pipe coiledwithin the water-tank and communicating with the expanding air-bag and aflexible pipe or hose communicating with the coil, substantially as andfor the purposes stated.

In a device of the class described, the combination of a machine-frame,an air-pump on the interior of the machine-frame, a foottreadleconnected with the air-pu mp, a spring for normally elevating thefoot-treadle, an expanding air-bag communicating with the pump, aone-way valve between the pump and an air-bag, a netting to limit theexpansion of the air-bag, a detachable water-tank in the machine-frame,means for applying heat to the tank, a thermometer on the tank, a coilof pipe within the tank communicating with the expanding bag, a hose,two tubes communicating with the hose and entering into a vessel, avessel for containing liquid and having said tubes admitted therein, andmeans for regulating the How of air from the hose to the vessel, for thepurposes stated.
